"Relaying" Multicast traffic to another interface

[aquadisco]

Without relying on PIM or any other multicast routing protocol, how would i relay multicast packets received on router interface A to interface B?

                         PC (multicast sender)  ----->   [Router]   ----->   (network cloud)         

                                                            I/F A                   I/F B

Hello Matthew,

- if the multicast traffic needs to be routed then PIM is needed

- if the source/receiver are on the same vlan, you can use a igmp querier instead of PIM.

Here is more info:

This is assuming you have IGMP snooping enabled.
